MATTHEW WHITE AND JAMES HENRY WHITE, OF LUTON, ENGLAND.

APPARATUS FOR WASHING AND SCR UBBING GASES.

To all whom it may concern.

Be it known that we, MATTHEW IVHITE and JAMEs HENRY VVHITE, both of 74 Inkerman street, Luton, Bedfordshire, England,

have invented a new and useful Improvement in Apparatus for Washing and Scrubbing Gases; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part hereof.

Our invention has reference to rotary apparatus for washing and scrubbing gases to separate dust and other impurities therefrom and to extract the tar and resinous matters so that the gas is finally discharged for use in a highly purified condition.

Primarily the invention is designed for use in connection with apparatus for the manufacture of suction gas from wood refuse and bituminous coal for power or heating purposes but its application to such use is not limited thereto as obviously it may be applied for scrubbing and washing other gases.

In order that our invention may be readily understood and carried into effect by those skilled in the art to which it appertains we will now proceed to describe the same fully for which purpose reference is to be had to the accompanying drawings in which Figure 1 is a side elevation partly in section of an apparatus constructed in accord ance with our invention. Fig. 2 is a ver-- tical section along the lines 1-1 of Fig. 1.

, Fig. 3 is a detail view hereinafter more particularly referred to.

In carrying our invention into practice we provide an approximately cylindrical casing a in which is journaled in appropriate hearings b a r'evoluble shaft (2 adapted to be driven by any suitable known means not shown. Keyed or splined to the shaft 0 are a plurality of disks 0? in the example illustrated in Fig. 2 two of said disks are shown but it is obvious that a greater number may be employed. Bolted to each side of the disks cl are a plurality of curved fins 6 arranged as shown in Fig. 1 in radial lines from the center to the periphery of the disks. Approximately conical casings f are mounted in the casing a in which the fins e are adapted to rotate as will be clearly seen with. reference to Fig. 2. The fins e as above stated are secured to each side of the disks d Specification of Letters Patent.

Application filed June 10, 1911.

Patented May '7, 1912. Serial No. 632,425.

projecting as shown in Fig. 3 alternately in opposite directions that is to say one fin is curved upward while the adjacent fin is curved downward. The disks (Z are provided with holes or apertures g and with slots h in the periphery to admit of the passage of the gases from one side of the disk to the other. The lower portions of the conical casing f are provided with outlet conduits 2' serving for the passage from the apparatus of the tar and water.

Arranged in any suitable position in the casing a as shown in Fig. 2 is a pipe jhaving a perforated cross piece is through which a spray of water may be introduced into the interior of the apparatus. Z is an inlet for I the gases to be washed.

The operation of an apparatus constructed in accordance with our invention is as follows :The gas from the generator is introduced into the apparatus at Z and passes upward as shown by the arrows in Fig. 2 and into the casing f where it is split up by the fins e on the rotating disk d and passes through the apertures g to the opposite side of the disks whence it passes into the space m from which it is conducted away for use. The gas in its passage through the apparatus is subjected to the action of the spray of water issuing from the member 7a the tar and other impurities being thus washed out of the gases and finally passing away from the conduits 2'.

It is to be noted that in our improved device the tar laden gas passes into the center where there are no running bearings and is taken out on the outside in a purified secure by scrubbing gases, the combination with an approximately cylindrical casing, of bearings carried by said casing, a revoluble shaft mounted in said bearings, a plurality of disks provided with a plurality of apertures and slots therein, keyed to said shaft,

fins secured laterally thereof to said disks and carried thereby said fins being alternately curved transversely with respect to the said disks in opposite directions, conical casings within which the curved fins are adapted to rotate, means for supply a spray of Water to the interior of the apparatus, and means for the discharge of the purified gas and for the tar and other impurities.

3. In an apparatus for washing and scrubbing gases, the combination of a casing provided with inlet and outlet means, a disk revolubly mounted within said casing with the said inlet and outlet means at each side of the plane thereof, and a plurality of fins secured laterally to said disk and curved transversely with respect thereto.

4. In an apparatus for washing and scrubbing gases, the combination of :1 revolubly mounted disk, disposed in a vertical plane, a plurality of fins secured laterally of said disk and carried thereby, the fins being curved laterally with respect to said disk and increasing in length from the periphery of said disk toward the center thereof, a frusto conical shell positioned adjacentthe said fins, and a conduit positioned in alinelnent with said frusto conical shell and fins at the lower ends thereof to carry away matter disposed thereon responsive to the force of gravity.

, In testimony whereof we afiix our signatures in presence of two witnesses.
